    run a can of Seafoam! and then do the intake treatment as well.. That really will help the most. There are a bunch of threads on the site that talk about seafoam and its benefits!

    x2 on the SEAFOAM when added to the fuel tank, and cleaning the throttle body & intake... their entire line of products has never caused me any problems (with seals, gaskets, o-rings. etc.).

    Are automobile manufacturers advocating the use of fuel and engine additives for their products? There is a wise old adage. "If it ain't broke don't fix it". I realize people have an innate compulsion to tinker with and screw around with things and have always been tempted by magical elixirs. Octane boosters, oil additives, fuel additives etc....Me, I don't spend my $$$ on fuel or engine additives or the myriad of products and snake oils out there that claim to do this or that unless the manufacturer recommends a products use. If there were additives that worked wonders I am sure every engine manufacturer would recommend them. But to each his own.

    The FIRST place I ever saw Seafoam for sale was at a GM stealership...It was THE recommended top end cleaner they sold in the 80's...

    One good thing about the the better additives ( Seafoam ) is that it will remove any water that has formed in your gas tank from condensation. Since your trucks been sitting for 10 months I would add Seafoam to the gas tank, take off the throttlebody and clean both sides with a spray throttlebody cleaner like CRC or Seafoam t/body cleaner and a old soft toothbrush, as I've said before on this site DON'T use carb cleaner. I would also use the Seafoam spray to clean inside the intake maniflod. If you go to Seafoam.com its shows how to use there products.

    I think that I understand from whence you are coming. But there are times when additives are necessary (and/or useful). One example, just mentioned here, is "water in the fuel".

    Ethanol (matters not whether it's 10% or 85%) contains alcohol... and alcohol attracts moisture... which can eventually lead to "product separation". It is that moisture/water which can corrode/damage metal parts. So using SEAFOAM, not only as a "cleaner" but also to mitigate "water in the fuel" makes sense. Some experts say that fuel (ethanol especially) can degrade within a matter of 90 days.

    There's also the problem of moisture in the OIL... each time there's a TEMP change/difference between the AIR and interior engine... condensation forms. Typically, it gets burned off / evaporates when the engine heats up... but many "short trips" (with cooling in between them) can degrade engine lubrication... so a little SEAFOAM is useful there as well (depending on one's driving habits).

    Then too, there's the matter of buying a USED vehicle. For example; I bought my '04 Silverado and also my wife's '00 Buick Century "used". Her Century exhibited "noisy lifters"... when started, until the engine completely warmed-up. I attributed such behavior to "sticky" lifters. So, I changed the OIL and added SEAFOAM... within 500 miles of driving, there was no longer any "noise" from the lifters (even in the dead cold of winter).

    Also there are additives for the coolant system. GM dealers even use "stop leak pellets" (made by BARS, IIRC)... to address minor seepage issues.

    But, back to your point:

    I would not go about experimenting with "additives" just for the hell of it... I always try to determine if there's a need for same.

    ...the above is just my 2cents, YMMV
